"Still thinking about Paris and my friend Thomas that we lost in the tragedy," Bieber wrote on Monday. "He was part of the team for years and I wish I would've had more time to thank him. Make sure to appreciate people while you have them. Thanks Thomas for everything you did for me. You are appreciated and missed. Thoughts and prayers are with your family & friends."

Ayad was named as one of 89 individuals killed in a mass shooting at the Eagles of Death Metal concert on Friday, the same day that Bieber released his new album, Purpose.
